| Abstract: |
This study employs construction wastes as the main materials to develop the recycling aggregate, which meets the specifications of green building materials, using the cold-bonding technique instead of sintering method in light of the issues of reduction of waste, energy, and CO2 footprint. Specifically, the cold-bonding technique incorporates the principles of the cement chemistry and composite material to develop the recycling aggregate. The results show that the specific gravity of cold-bonding recycling aggregate is in the range of 1.73 to 1.81; the absorption capacity is 14.9 to 16.7%; the bulk density (unit weight) is 1103 to 1176 kg/m³; the voids is 35.0 to 36.6%; the particle cylindrical crushing strength ranges is 12.09 to 19.36 MPa. The developed cold-bonding recycling aggregate could increase the reuse and recycling of construction wastes, reduce the energy |
